Abstract

Methods and apparatus for separating vapor from refined cellulosic material are disclosed. The method includes discharging the refined cellulosic material downwardly through an inlet opening into a discharge chamber maintained at substantially the same pressure as the refiner, deflecting the vapor laterally with respect to that cellulosic material, passing the vapor through the discharge chamber at a flow rate of less than 15 meters/sec. so that the cellulosic material carried by the vapor is separated from the vapor by sedimentation, and discharging the cellulosic material from the discharge chamber. The apparatus includes a discharge chamber with an inlet and an outlet, and a portion laterally disposed with respect to the inlet, a conveyor for moving the cellulosic material laterally towards the discharge chamber outlet to create a substantially gas-tight plug of cellulosic material in order to maintain the discharge chamber substantially at the pressure at which the cellulosic material is refined, the conveyor permitting the vapor to pass laterally with respect to the inlet opening and a vapor outlet located in the portion of the discharge chamber laterally disposed with respect to the inlet.
